COMBINED CHURN A D BUTTER-WORKER.

SPECIFICATION forming part of Letters ?atent No. 539,570, dated. m21,1895.

Application filed October 15, 1894- To all whom it may concern:

Be it known that 1, CHARLES .8. BROWN, of Lake Mills, in the county ofJefferson and State of Wisconsin, have invented a new and usefulImprovement in a Combined Churn and Butter-Worker, of which thefollowingis a description, reference being had to the accompanyingdrawings, which are a part of this specification.

My invention relates toimprovements in a churn and butter worker of theclass in which each machine'is adapted for use either as a churn or as abutter worker; the mechanism being so constructed that by certainchanges,

which can be made at will, in the position and in the relation of partsto each other, the machine can be used either as a churn or as a butterworker.

The invention consists of the mechanism and its parts and combinations,as herein described and claimed, or their equivalents.

In the accompanying drawings, Figure l is a side elevation of thecomplete machine. Fig. 2 is an elevation of the front end of themachine. Fig. 3 is a central horizontal section of a fragment of thedrum with fragments of the roller segments therein and mechanism relatedmechanically thereto, shown partly in Fig. at is a transverse section ofthe drum and roller segments medially, partof the drum being broken awayfor convenience of illustration. Fig. 5 is a detail of aliquid-discharging valve located in the drum. Fig.6 is a detail of thejournal-box and gland in connection with the journal of aroller-segment.

The drum 10 is provided with closed front and rear ends 11, 11', andgudgeons 12, ,l2'are fixed to the ends of the drum, by which the drum issupported revolubly on the frame A. The drum is also provided with anaperture closed by the door 13, which is secured in place detachably bythe cam buttons 14. Through this door-closed aperture access is had tothe interior of the drum, for inserting and removing the contentsthereof. The drum is also provided interiorly with longitudinallydisposed slash-boards or buckets 15 arranged at distances apart, andprojecting inwardly radially from the shell of the drum. These bucketsare provided with apertures 16,

Serial No. 525,852. (No model.)

adjacent to the shell of the drum, adapted for the escape of milk orwater thereth'rough. Thedrum is also provided with a series of aperturesarranged circumferentially in a common radial plane, preferably near oneend of the drum and closed by the spring-actuated valves 17, each valvebeing provided with an outwardly projecting stem18. These valveclosedapertures are adapted for the escape of milk or water/from the drum,when it is used as a butter worker.

In the drum there are two corrugated segmental butter-working devices19, 19. These devices consist of two roller segments, substantially aslong as the chamber of the drum, each being provided with arbors 20, 21by which they are mounted, parallel with the axis of the drum, andadjacent to but opposite each other, the arbors being therefor journaledin the ends of ,the drum. The arbors 20 at the front, extend through theend ll of the drum, while the arbors 20 at the rear are journaled liquidtight in the end or head 11 of the drum. These roller segments consistpreferably of segmental shells corrugated longitudinally on their outerarc surfaces, and these shells are fixed on radial se mental blades orframes 21, 21, which frames are rigidly secured to the arbors 20, 20'.These roller segments are so disposed in the drum that their aresurfaces are adjacent and opposite to each other, forming complementarypressure surfaces, between which the butter, falling from above, isreceived and is passed between them as these surfaces. are oscillateddownwardly. For oscillating these roller segments concurrently, thesegments are provided with segmental racks 22, 22 fixed on the arbors 20outside of the drum, which racks are reversely disposed and mesh witheach other. These arbors are also each provided with a radiallyprojecting stem or arm 23, 23' one of which 23 projects from the arborat a right angle to the chord of the arc of the shell 22, and the other21' projects from the other arbor 20, at an angle oblique to the chordof the other are 22. This variation in the angle of the arms 23, 23' tothe chords of the arcs 22, 22 is provided so that when one of these armsis tilted by passing a relatively 'fixed tripping arm, the other armwill be thrown into position to engage the same tripping arm, and inpassing it will throw the first arm again into position to be engaged bythe tripping arm. Stops 24, 24 are fixed in and project from the end ofthe drum, which stops are adapted to engage the arm 23' and limit themovements of the arms and the segments 19, 19.

For tripping the arms 23, 23, and thereby oscillating the rollersegments 19, 19' an arm 25 is pivoted on the frame and is provided withan anti-friction roller 26 in its free extremity, which rolleris adaptedto receive the thrust and bearing of the arms 23, 23, when the trippingarm 25 is in the path of the arms 23,23 in the position shown in Fig 2.For putting this tripping arm into or throwing it out of action, it isconnected by a link 27 to a hand lever 28 pivoted at one extremity to aprojecting portion of the frame. The hand lever 28 is slightly elasticand is provided with a little rib 29 adapted to enter notches thereforin the frame, and thereby to be locked in position.

At the front end of the machine the gudgeon 12 is integral with thespider 30, the extremities or feet of which spider are secured rigidlyto the end or head 11 of the drum near its periphery. Thelegs of thisspider are offset a little from the head 11, so as to provide spacebetween them and the head, for the racks 22, 22.

At the rear end of the drum the gudgeon 12' is secured rigidly to theend or head 11 centrally. This gudgeon 12 is provided with a loosepulley 31 and a loose driving pulley 32, which pulley is provided with ahub having a sprocket wheel 33 thereon. A collar 3-ct splined on thegudgeon 12' is adapted to clutch the hub of the pulley 32 and hold thedrum to revolution with the pulley. A countershaft 35, journaled in theframe, is provided with a sprocket wheel 36, onwhich asprocket belt 37runs from the sprocket wheel 33. A pinion 38, splined on thecounter-shaft 35, meshes with the annular rack 39 fixed on the head ofthe drum. A lever handle 40 pivoted at one extremity to the frame, isprovided with a spanning finger that rides in an annular groove in thecollar 34, and is adapted for shifting the collar 34 into and out ofclutch with the hub of the pulley 32. A link ell, pivoted at oneextremity to the lever-handle 40, is provided at its other extremitywith a spanning finger riding in an annular groove in the hub of thepinion 38, whereby the lever handle is adapted also for shifting thepinion 38 into and out of mesh with the rack 39. The lever handle 40 isslightly elastic and is thereby adapted to take into and be releasedfrom a rack 42 on the frame, whereby the lever-handle is releasablylocked in position. hen in the position shown in Fig. 3 in which thepinion 38 is in mesh with the rack 39, the motion communicated throughthe pulley 32, the sprocket belt 37, and the pinion 38, to the drum,produces a comparatively slow rotation of the drum, and is such as isrequired when the machine is in use as a butter worker. When the machineis to be used as a churn, the lever handle 40 is shifted so as torelease the pinion 38 from the rack 39 and to clutch the gudgeon 12rotatably to the pulley 32, whereby the motion of the pulley 32 iscommunicated directly to the drum, thereby revolving it more rapidly, asis desirable when used as a churn.

A rigid strap or plate 43, curved to corre spond with the circumferenceof the drum, is fixed rigidly on radial arms 4st on the rockshaft 45,which rock-shaft is journaled in the frame, and a hand lever 46 pivotedmedially on the frame is connected by a link 47 to a radial arm 48 fixedon the rock-shaft 45, whereby the plate 43 may be lifted into or droppedout of the path of the valve-stems 18. This plate when in the path ofthe valvestems is adapted to lift the valves 17 as they pass the plate,during the rotation of the drum and thereby permit milk or water toescape therefrom, the plate being located be low the drum therefor.

In Fig. 6 a suitable journal box 49 and gland 50, is shown, for packingthe journals 20 in the head 11. Any other equivalent means of packingthe journals may be used.

WVhen the machine is used as a churn it is desirable that the rollersegments 19, 19 should remain stationary relative to the drum, and forthis purpose a convenient means of securing them stationary in adesirable position is a pin thrust through an aperture 51. in the stem23 and inserted in an aperture 51 in the head 11, the stem being rotatedto a position that the apertures 51 and 51 register with each other.

Vhen this machine is used as a churn the operation in a general way isas follows: Milk being put into the drum and the aperture thereforclosed by the door 13, and the roller segments 19, 19 being locked inposition by a pin in the apertures 51, 51', the tripping arm 25 beingalso out of the path of the stems 23, 23, and the plate 43 dropped belowthe path of the valve stems 18, the pulley is clutched to the gudgeon 12and the drum is revolved with comparative rapidity by motioncommunicated to it through the pulley 32. This is continued until thebutter is separated from the milk. Thereupon the milk being removed fromthe drum, either through the door aperture or by lifting one or more ofthe valves 17, the machine is made to serve as a butter worker, bywithdrawing the pin in the apertures 51, 51', putting thetrippingarm 25into the path of the stems 23, 23, and shifting the pinion 38 into meshwith the rack 39, thereby at the same time releasing the gudgeon 12'from the pulley 32, and by lifting the plate 43 into the path of thevalve stems 18. When the mechanism is thus disposed, the motioncommunicated to the drum will be comparatively slow. The butter being atthe bottom of the drum is carried up by the buckets ICC hearly to thetop and is dumped. therefrom on to'the segments 19, 19 which segmentsbeing in the position shown in Figs. 2 and 3 are oscillated by the stem23 coming in contact with and passing the tripping arm 25, whereby thebutter is pressed and passed downwardly between the segments, falling onthe bottom of the drum, to be again carried tov the top by thesucceeding bucket and to fall on the segments being then in a similarposition relative to each other, and to be again passed down between thesegments by the oscillating thereof, caused by the stem 23 coming incontact with and passing the tripping arm 25, as the drum revolves.

The rack 42 is broken away on Fig. 1, to show mechanism at the rearthereof.
